TEW4610 Datasheet, PDF (1/1 Pages) Filtran LTD – ISDN S-BUS Input/Output Transformer

ISDN S-BUS
Input/Output Transformer
The 4 wire interface between
Subscriber Terminals and The
Network Temination has been
standardised by CCITT recom-
mendation I.430. It uses a pas-
sive bus which provides
separate receive and transmit
loops operating at 192 Kbits/s.
The TEW4610 has been ap-
proved for use with the INTEL
S-bus interface device S29C53.
